A device used for flattening balls of dough made from masa harina or wheat flour into thin, round discs suitable for cooking tortillas is typically made of cast iron, aluminum, or wood. These devices consist of two flat plates, one of which is fixed to a base and the other hinged to allow it to press down upon the dough. A simple lever mechanism applies the necessary force to achieve the desired thinness. Electric versions, while less common, offer automated pressing for higher-volume production.
This tool significantly simplifies and speeds the process of tortilla making, ensuring uniform thickness and shape, which contributes to even cooking. Prior to widespread availability of these devices, tortillas were traditionally flattened by hand using a rolling pin or by clapping between the palms. The adoption of this kitchen aid has allowed for greater efficiency and consistency, particularly beneficial for both home cooks and commercial kitchens. Its rise in popularity parallels the increased accessibility of ingredients for making tortillas beyond traditional geographic areas.
